Eight years ago Louisiana's then Wildlife and Fisheries Secretary Robert Barham warned the feral hog population was exploding in such massive numbers that they may one day be rooting up Huey Long's grave on the Capitol grounds.
Since then the feral hog population in Louisiana has gone from 600,000 to nearly 1 million, about the same as the combined human population for the state's largest four cities - New Orleans, Baton Rouge, Shreveport and Metairie, a suburb of New Orleans.
